This is a feature, not a bug
Why did Linux systems go for capitals in the home folder? It’s actually kind of annoying and takes extra key presses.
…A while later “XDG Base Directory Specification”
XDG specifies the capital names, but to be nitpickingly technically precise, linux systems don’t do this. It mostly is done by the distribution maintainers, and the XDG specs. A base system does not usually have a notion of anything beyond your $HOME.
Try adding a user: sudo adduser basicuser
. If you ls -al ~basicuser
you will see it’s almost empty, just the .bashrc (or in my fedora, there’s some .mozilla crap in /etc/skel that also gets bootstrapped).
Also, I constantly name files in the same directory the same thing except for case. In my ~/tmp directory I have unrelated foo.c (C source) and foo.C (C++ source).
Why not .cpp for C++? I don’t use C++, but I thought that was the standard.
